diamonds are concentrated form of carbon crystal
September 2nd, 2011Diamond is concentrated form of carbon crystal
As we know, diamond is a kind of pure carbon in its most concentrated form. Diamond is made from carbon, completely is a chemical element of all life forms of the most fundamental problem there are some impurities like nitrogen, boron. Diamond is different from other close chemical as graphite and lonsdaleite Cousins, these two diseases are composed of the element of carbon. But what makes diamond unlike these close cousin is carbon atoms specially arranged it crystal structure. A crystal, as we know, is an entity, if formed from the connection of atoms elements or compounds repetitive arrangement. As you know, a crystal is an entity, with smooth face, the external blocks confined in the relatively small number of atoms are arranged to a simple numerical combination of elements.
A neutral carbon atoms can be composed of six protons and electrons that are arranged in its six surrounding the nucleus of atoms. A carbon atom electronic four valence, can form bonds and two hydrogen atoms. When we talk of graphite, the carbon atoms only three of the four covalence bond with their neighboring carbon cause a connection single carbon atoms flat leave these layers weakly connected to one another, and easy to use, they are separate is graphite so slippery. But in diamond, each carbon will share all four available electronic and adjacent carbon atoms so formed electronic key is the strongest known chemical links to a diamond its hardness. So repetitive structure unit diamond consists of eight atomic fundamentally arranged in a cube. So that the diamond crystals can appear in various shapes. So diamond crystals cube, octagonal, dodecahedra even comprehensive all shapes. These two kinds of special form, platform macle forms, it is actually a composite crystal and printing crystals, one has rounded surface, even slender shape.
The real diamond crystals may not have a completely smooth face. There may be slight produced impression on etching, natural crystal, dissolution, or part of the natural growth of crystallization. But a diamond may famous hardness, is that really resistance measurement of substance was scratched. So only a diamond can scratch another diamond. Therefore, we said that diamond is the hardest substance known to the nature. So hardness for its durability diamond may cause. Although diamonds are not fragile and easy to be broken, but it can also fracture or rupture. The answer is hidden in the perfect crystal structure. Because the structure of the diamond has some weakness in the plane can be split. A diamond have a perfect cleavage in all four directions so it will along this line of thought and tidy and not in the winding or irregular fashionable, because diamond crystals along the chemical bonds less than though other aircraft facial direction. Its function is to advantage for diamond knife. So in true form diamonds are concentrated form of carbon crystals.
